Boeing has patented technology to 3D print objects while levitating in space. Boeing plans to 3D print aircraft parts using this technology. For more details check - http://patentyogi.com/obzxx
Multiple3D printers are used to simultaneously print various features. The printing material has diamagnetic properties. When super-cooled becomes a super-conductor.
First, a small quantity of the printing material called nugget is ejected into space. By creating magnetic fields, the nugget is held in space by levitating it. Now, further deposition of printing material can be made from any direction in space.
This technique offers many unique advantages.
1. Material can be deposited right beneath the nugget.
This is not possible in conventional 3D printers, which follow a bottoms-up printing technique.
2. Additional magnetic fields are used to rotate the nugget to any orientation. This allows fabrication of more complex features
3. Even acoustic levitation can be used to levitate nugget
4. Simultaneous use of multiple print heads increases the speed of printing objects many fold

A Video made for the Mid-Review of my M.ArchThesis titled Sub-Additive at Cornell University. Sub-Additive Manufacturing explores a three dimensional deposition of concrete printing material on a mechanically shaped substructure of reusable aggregate. Concrete material is extruded with a custom 3D printer, using three dimensionally curved deposition paths on top of the shaped gravel. By printing in three dimensions, the time consuming process of corbelling is replaced by spatial concrete arching. Creating curvature in concrete with this method increases the speed over typical 3D printing practices, can produce double curved geometries which are structurally optimized, does not require formwork during assembly of shell components, and eliminates waste material.

3-D printing, high-speed navigation, and a magic mirror are some of the technologies to come from new computer chips with advanced spatial sensing. VOA's Mike O'Sullivan reports from San Francisco, where technology start-ups that have partnered with chip-maker Intel showed off their products.

Who doesn’t want to interact with their own favorite picture book? A new software platform from MentalCanvas, a company funded by the National Science Foundation’s Small Business Innovation Research program, may soon let you do just that.
The technology allows users to draw like you would with pen and paper, except when you put the pen down, the sketch is viewable from multiple directions -- like having access to every camera angle.
“I think of it as a spatial drawing,” says JulieDorsey, computer scientist at Yale and founder of Mental Canvas, who has a long history of support from NSF. “Fundamentally, the technology expands on what we think of as a conventional drawing or sketch.”
Building the platform meant developing a new media type, as well as a set of tools to design and interact with this media form. It incorporates elements of computer-aided design, 2D and 3D graphics, software engineering, and human-computer interaction.
To demonstrate the software’s capabilities, Mental Canvas has applied the technology to an illustrated book called “The Other Side” by Istvan Banyai. The book is a modern-day graphic novel, taking the reader on a complex, visual journey. With Dorsey’s technology rendering the story in 3D, the effect is immersive.

3D printing, also known as additive manufacturing (AM), refers to various processes used to synthesize a three-dimensional object. In 3D printing, successive layers of material are formed under computer control to create an object. These objects can be of almost any shape or geometry and are produced from a 3D model or other electronic data source. A 3D printer is a type of industrial robot.
At Virginia Polytechnic Institute and State University (VT), Christopher Williams heads the effort to further advance 3-D printing. Williams is using a process called binder jetting in which an inkjet printer selectively jets glue into a bed of copper powder, layer-by-layer. The printed copper product is then taken to a furnace to fuse the particles together
With support from the National Science Foundation (NSF), Williams is addressing a major challenge in the 3-D copper printing process, which is to eliminate the porosity that develops in the part during the process. These microscopic pockets of air weaken the finished product.
Williams's goal is to create an additive manufacturing process for copper that would be practical for widespread use. If successful, the results gleaned from this project can also be used to educate future engineers in designing systems with 3-D printing. Beyond the already functioning “3-D printing vending machine” available to students at VT, researchers hope to integrate their findings into an undergraduate/graduate additive manufacturing course, as well as summer workshops for K-12 science, technology, engineering and mathematics (STEM) teachers. These proposed programs will not only instruct students through inquiry-based learning methods but also study how teacher/student perceptions of manufacturing evolve. 27 July 2015

Seamless full color holographic printing method based on spatial partitioning of SLM. Youngmin Kim et al (2015), Optics Expresshttp://dx.doi.org/10.1364/OE.23.000172
The holographic wavefront printer decodes the wavefront coming from a three-dimensional object from a computer generated hologram displayed on a spatial light modulator. By recording this wavefront as an analog volume hologram this printing method is highly suitable for realistic color 3D imaging. We propose in the paper spatial partitioning of the spatial light modulator to perform mosaic delivery of exposures at primary colors for seamless reconstruction of a white light viewable color hologram. The method is verified for a 3 × 3 color partitioning scheme by a wavefront printer with demagnification of the light beam diffracted from the modulator.

// AbstractRecently, researchers started to engineer not only the outer shape of objects, but also their internal microstructure. Such objects, typically based on 3D cell grids, are also known as metamaterials. Metamaterials have been used, for example, to create materials with soft and hard regions.
So far, metamaterials were understood as materials—we want to think of them as machines. We demonstrate metamaterial objects that perform a mechanical function. Such metamaterial mechanisms consist of a single block of material the cells of which play together in a well-defined way in order to achieve macroscopic movement. Our metamaterial door latch, for example, transforms the rotary movement of its handle into a linear motion of the latch. Our metamaterial Jansen walker consists of a single block of cells—that can walk. The key element behind our metamaterial mechanisms is a specialized type of cell, the only ability of which is to shear.
In order to allow users to create metamaterial mechanisms efficiently we implemented a specialized 3D editor. It allows users to place different types of cells, including the shear cell, thereby allowing users to add mechanical functionality to their objects. To help users verify their designs during editing, our editor allows users to apply forces and simulates how the object deforms in response.

3D printing

3D printing, also known as additive manufacturing (AM), refers to various processes used to synthesize a three-dimensional object. In 3D printing, successive layers of material are formed under computer control to create an object. These objects can be of almost any shape or geometry and are produced from a 3D model or other electronic data source. A 3D printer is a type of industrial robot.

Futurologists such as Jeremy Rifkin believe that 3D printing signals the beginning of a third industrial revolution, succeeding the production line assembly that dominated manufacturing starting in the late 19th century. Using the power of the Internet, it may eventually be possible to send a blueprint of any product to any place in the world to be replicated by a 3D printer with "elemental inks" capable of being combined into any material substance of any desired form.

3D printing in the term's original sense refers to processes that sequentially deposit material onto a powder bed with inkjet printer heads. More recently, the meaning of the term has expanded to encompass a wider variety of techniques such as extrusion and sintering-based processes. Technical standards generally use the term additive manufacturing for this broader sense.

Five ways Bioengineers want to use 3-D Printing

Five ways Bioengineers want to use 3-D Printing

Five ways Bioengineers want to use 3-D Printing

Now that 3D printing has made it easier to generate custom-made prosthetics, bioengineers are looking ahead at manufacturing actual cellular material. Such technology could be the basis for personalized biomedical devices; tissue-engineered skin, cartilage, and bone; or even working bladders.
In a Trends in Biotechnology special issue on biofabrication, publishing August 17, researchers review and consider the progress made in 3D bioprinting and what might be possible in the decades--or years--ahead.
1. Made-to-Order Organs-on-a-Chip
"Organs-on-a-chip"--3D microengineered systems that mimic the structure and function of human tissue--are a strong contender in the race to deliver inexpensive and efficient personalized medicine. Lung, gut, and pancreatic tissue have already been grown from human stem cells on the chips, which allow researchers to study physiological differences in these cells between patients as well as screen for drugs.
Manufacturing challenges exist to quickly expand the use of the technology, but 3D printing could reduce the labor and costs necessary to build, seed, and meet the demand for chips
2. Skin Manufacturing
Printed skin made from cells set down on a collagen gel showed the presence of intercellular connections and biologically normal cell markers 10 days after cultivation. In another study, researchers have been able to grow blood vessels in this sheet of cells. Skin bioprinting is closer to reality than one would think, but researchers are only at the beginning of considering the designs necessary to help patients, especially those with burns or chronic wounds.
3. Facial Reconstruction
While bone, cartilage, skin, muscle, blood vessels, and nerves have all been printed in the laboratory, constructing more complex designs that can be implated in patients is still in development. Craniofascial reconstruction, which would benefit people with cancer or who have experienced facial injuries, seems to be an obvious candidate to pursue because of the amount of work already done on these cell types. In the short term, 3D printed scaffolds could be used to improve spot defects in the jaw or other areas of the face.
4. Multi-Organ Drug Screens
3D bioprinting is demonstrating that precise models can improve the way we evaluate new drugs, such as by generating "organoids" made up of multiple cell types, as well as a tumor model with engineered blood vessels. While such approaches could make it possible to quickly monitor drug interactions in real time in multiple organs, much more iteration (e.g., adding blood vessels, connecting organ models) will be needed to realize this vision.
5. Plug-in BloodVessels
Efforts to create 3D blood vessel networks within bioengineered tissues--which would be necessary to ensure tissue survival after implantation and an accurate replication of human anatomy--have focused on stacking 2D layers of cells or bioprinting 3D networks, which allows for high levels of spatial control. One challenge is to create tissues with blood vessel networks that could directly connect to a patient's arteries or veins.

A Video made for the Mid-Review of my M.ArchThesis titled Sub-Additive at Cornell University. Sub-Additive Manufacturing explores a three dimensional deposition of concrete printing material on a mechanically shaped substructure of reusable aggregate. Concrete material is extruded with a custom 3D printer, using three dimensionally curved deposition paths on top of the shaped gravel. By printing in three dimensions, the time consuming process of corbelling is replaced by spatial concrete arching. Creating curvature in concrete with this method increases the speed over typical 3D printing practices, can produce double curved geometries which are structurally optimized, does not require formwork during assembly of shell components, and eliminates waste material.

Who doesn’t want to interact with their own favorite picture book? A new software platform from MentalCanvas, a company funded by the National Science Foundation’s Small Business Innovation Research program, may soon let you do just that.
The technology allows users to draw like you would with pen and paper, except when you put the pen down, the sketch is viewable from multiple directions -- like having access to every camera angle.
“I think of it as a spatial drawing,” says JulieDorsey, computer scientist at Yale and founder of Mental Canvas, who has a long history of support from NSF. “Fundamentally, the technology expands on what we think of as a conventional drawing or sketch.”
Building the platform meant developing a new media type, as well as a set of tools to design and interact with this media form. It incorporates elements of computer-aided design, 2D and 3D graphics, software engineering, and human-computer interaction.
To demonstrate the software’s capabilities, Mental Canvas has applied the technology to an illustrated book called “The Other Side” by Istvan Banyai. The book is a modern-day graphic novel, taking the reader on a complex, visual journey. With Dorsey’s technology rendering the story in 3D, the effect is immersive.

3D printing, also known as additive manufacturing (AM), refers to various processes used to synthesize a three-dimensional object. In 3D printing, successive layers of material are formed under computer control to create an object. These objects can be of almost any shape or geometry and are produced from a 3D model or other electronic data source. A 3D printer is a type of industrial robot.
At Virginia Polytechnic Institute and State University (VT), Christopher Williams heads the effort to further advance 3-D printing. Williams is using a process called binder jetting in which an inkjet printer selectively jets glue into a bed of copper powder, layer-by-layer. The printed copper product is then taken to a furnace to fuse the particles together
With support from the National Science Foundation (NSF), Williams is addressing a major challenge in the 3-D copper printing process, which is to eliminate the porosity that develops in the part during the process. These microscopic pockets of air weaken the finished product.
Williams's goal is to create an additive manufacturing process for copper that would be practical for widespread use. If successful, the results gleaned from this project can also be used to educate future engineers in designing systems with 3-D printing. Beyond the already functioning “3-D printing vending machine” available to students at VT, researchers hope to integrate their findings into an undergraduate/graduate additive manufacturing course, as well as summer workshops for K-12 science, technology, engineering and mathematics (STEM) teachers. These proposed programs will not only instruct students through inquiry-based learning methods but also study how teacher/student perceptions of manufacturing evolve. 27 July 2015

Seamless full color holographic printing method based on spatial partitioning of SLM. Youngmin Kim et al (2015), Optics Expresshttp://dx.doi.org/10.1364/OE.23.000172
The holographic wavefront printer decodes the wavefront coming from a three-dimensional object from a computer generated hologram displayed on a spatial light modulator. By recording this wavefront as an analog volume hologram this printing method is highly suitable for realistic color 3D imaging. We propose in the paper spatial partitioning of the spatial light modulator to perform mosaic delivery of exposures at primary colors for seamless reconstruction of a white light viewable color hologram. The method is verified for a 3 × 3 color partitioning scheme by a wavefront printer with demagnification of the light beam diffracted from the modulator.

Now that 3D printing has made it easier to generate custom-made prosthetics, bioengineers are looking ahead at manufacturing actual cellular material. Such technology could be the basis for personalized biomedical devices; tissue-engineered skin, cartilage, and bone; or even working bladders.
In a Trends in Biotechnology special issue on biofabrication, publishing August 17, researchers review and consider the progress made in 3D bioprinting and what might be possible in the decades--or years--ahead.
1. Made-to-Order Organs-on-a-Chip
"Organs-on-a-chip"--3D microengineered systems that mimic the structure and function of human tissue--are a strong contender in the race to deliver inexpensive and efficient personalized medicine. Lung, gut, and pancreatic tissue have already been grown from human stem cells on the chips, which allow researchers to study physiological differences in these cells between patients as well as screen for drugs.
Manufacturing challenges exist to quickly expand the use of the technology, but 3D printing could reduce the labor and costs necessary to build, seed, and meet the demand for chips
2. Skin Manufacturing
Printed skin made from cells set down on a collagen gel showed the presence of intercellular connections and biologically normal cell markers 10 days after cultivation. In another study, researchers have been able to grow blood vessels in this sheet of cells. Skin bioprinting is closer to reality than one would think, but researchers are only at the beginning of considering the designs necessary to help patients, especially those with burns or chronic wounds.
3. Facial Reconstruction
While bone, cartilage, skin, muscle, blood vessels, and nerves have all been printed in the laboratory, constructing more complex designs that can be implated in patients is still in development. Craniofascial reconstruction, which would benefit people with cancer or who have experienced facial injuries, seems to be an obvious candidate to pursue because of the amount of work already done on these cell types. In the short term, 3D printed scaffolds could be used to improve spot defects in the jaw or other areas of the face.
4. Multi-Organ Drug Screens
3D bioprinting is demonstrating that precise models can improve the way we evaluate new drugs, such as by generating "organoids" made up of multiple cell types, as well as a tumor model with engineered blood vessels. While such approaches could make it possible to quickly monitor drug interactions in real time in multiple organs, much more iteration (e.g., adding blood vessels, connecting organ models) will be needed to realize this vision.
5. Plug-in BloodVessels
Efforts to create 3D blood vessel networks within bioengineered tissues--which would be necessary to ensure tissue survival after implantation and an accurate replication of human anatomy--have focused on stacking 2D layers of cells or bioprinting 3D networks, which allows for high levels of spatial control. One challenge is to create tissues with blood vessel networks that could directly connect to a patient's arteries or veins.

Boeing has patented technology to 3D print objects while levitating in space. Boeing plans to 3D print aircraft parts using this technology. For more details check - http://patentyogi.com/obzxx
Multiple3D printers are used to simultaneously print various features. The printing material has diamagnetic properties. When super-cooled becomes a super-conductor.
First, a small quantity of the printing material called nugget is ejected into space. By creating magnetic fields, the nugget is held in space by levitating it. Now, further deposition of printing material can be made from any direction in space.
This technique offers many unique advantages.
1. Material can be deposited right beneath the nugget.
This is not possible in conventional 3D printers, which follow a bottoms-up printing technique.
2. Additional magnetic fields are used to rotate the nugget to any orientation. This allows fabrication of more complex features
3. Even acoustic levitation can be used to levitate nugget
4. Simultaneous use of multiple print heads increases the speed of printing objects many fold

Awesome Breakthrough in 3-D Printing Technology

3D printing, also known as additive manufacturing (AM), refers to various processes used to synthesize a three-dimensional object.

These objects can be of almost any shape or geometry and are produced from a 3D model or other electronic data source. A 3D printer is a type of industrial robot.
At Virginia Polytechnic Institute and State University (VT), Christopher Williams heads the effort to further advance 3-D printing. Williams is using a process called binder jetting in which an inkjet printer selectively jets glue into a bed of copper powder, layer-by-layer.

With support from the National Science Foundation (NSF), Williams is addressing a major challenge in the 3-D copper printing process, which is to eliminate the porosity that develops in the part during the process. These microscopic pockets of air weaken the finished product.
Williams's goal is to create an additive manufacturing process for copper that would be practical for widespread use.

3D printing

3D printing, also known as additive manufacturing (AM), refers to various processes used to synthesize a three-dimensional object. In 3D printing, successive layers of material are formed under computer control to create an object. These objects can be of almost any shape or geometry and are produced from a 3D model or other electronic data source. A 3D printer is a type of industrial robot.

Futurologists such as Jeremy Rifkin believe that 3D printing signals the beginning of a third industrial revolution, succeeding the production line assembly that dominated manufacturing starting in the late 19th century. Using the power of the Internet, it may eventually be possible to send a blueprint of any product to any place in the world to be replicated by a 3D printer with "elemental inks" capable of being combined into any material substance of any desired form.

3D printing in the term's original sense refers to processes that sequentially deposit material onto a powder bed with inkjet printer heads. More recently, the meaning of the term has expanded to encompass a wider variety of techniques such as extrusion and sintering-based processes. Technical standards generally use the term additive manufacturing for this broader sense.
